Check out nocrotec.com for more info on these tubes. They all look ike zm57-series tubes which came with clear or tinted glass.
I've heard that some companies bought unlabeled tubes in bulk and resold them with their own labels. That may explain the zm1177 markings. 1177 tubes have 15.5 mm digits and use 2.5 ma versus 13 mm & 2 ma for the 57x tubes. The digit size difference is noticeable. Interesting find though. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
